BY i 5m ATTACHMENT ASSEMBLY FOR LOOP CONSTRUCTION FABRIC The present invention generally discloses certain improvements in my prior US. Pat. Nos. 2,402,568, 2,407,031 and 2,585,671. I

An object of the present invention is'to provide a loop foundation enabling connection of the material being formed to a flexible cloth attached to a roller to enable the material to be easily detached from the cloth by removing a connecting ele ment which has been inserted through aligned loops attached to the edge of the cloth and forming a portion of the edge of the material formed by employing the present invention.

Another object of the invention is to provide a loop foundation in which various patterns may be "formed by forming knotted loops which may be connected to-each other or certain loops surround a single point left free and otherwise arranged to provide numerous patterns and designs by using a single strand of material or by employing a plurality of strands of various colors thus facilitating the manufacture of material useful in constructing garments, curtains, tablecloths bed covers, lace collars, shawls and other material such as hosiery or the like where it is desired to provide a mesh material which will not run or unravel in the event the material is'cut.

Another important object of the present invention is to provide a loop foundation which is capable of formation by hand by the use of a single straight smooth needle or may be'manufactured on a machine similar to a fishnet machine such as disclosed in US. Pat. No. 98,461 issued Jan. 4, 1870.

Still another important object of the present invention is to provide a loop foundation capable of detachably connecting a plurality of strands of material employed in a knitting or weaving operation to enable the finished material to be disconnected from a takeup roller thus eliminating the necessity of cutting the finished material by the use of scissors or the like.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIG. 1 is a perspective view of the loop foundation of the present invention incorporated into a hand weaving machine;

FIG. 2 is an enlarged view illustrating the connection of the takeup roller cloth with the material;

FIG. 3 is a plan view of the construction of FIGS. 1 and 2;

and

FIG. 4 is a plan view of one embodiment of the material formed by employing the loop foundation of the present invention.

Referring now specifically to the drawings, the numeral generally designates a frame on which a plurality of threads or strands 12 are to be worked by weaving, forming knot loops in various patterns or the like with the frame including a pair of spaced side members 14 provided with a notch or the like 16 at one end thereof for removably receiving a roller 18 thereon. Attached to the roller is a flexible cloth 20 which is connected to the strands or threads 12 at one end and connected to the roller 18 at the other end. The cloth 20 is received in a substantially cylindrical flexible and resilient member 22 constructed of paper, plastic, metal or the like having an entrance slit 23 at one edge thereof for enabling passage of the cloth 20,

The slit 23 being defined by the resilient edges of the cylindrical tube 22 will frictionally engage the cloth 20 thus retaining tension thereon.

The edge of the cloth 20 is provided witha plurality of loops 24 thereon which receive a transversely extending connecting pin 26 or the like therethrough. The ends of the threads 12 are connected with the pin 26 by loops 28 which are defined by knots 30 or the like with the loops 28 being in alignment with the loops 24 thus connecting the threads 12 to the cloth 20. Removal of the connecting rod or pin 26 is accomplished by longitudinal movement of the pin in either direction. The pin may be provided with detachable end members 32 engaging the top ed es of the rails 14 and guiding the pin therealon or the ends 0 the pm 26 may be straight. Also, m some instzfilations, the connecting pin may be in the form of a flexible thread or web of material sufficient to enable a limited tension to be applied to the threads 12 such as occurs in forming knot loops or the like. 3

The loops 24 are formed in the same manner and connected to the edge of the cloth 20 in the same manner as disclosed in the previously mentioned patents in that a series of knots 34, all being the same, are formed from a single, continuous strand along the edge of the material.

Also, the knot loop 24 may be formed in various patterns such as illustrated in FIG. 4 in which the loops 24 are each knotted to a circular member 26 which is continuous with the loops with certain of the loops being free of connection and other of the loops being connected with adjacent loops 24' by knots 34' thus forming rosettes or other desired patterns such as a star or the like.

The loop foundation may be formed in rows of tightly looped strands in which each strand is knotted where it intersects and each loop is knotted where it intersects with strands or the loop foundation may be made in an open mesh type arrangement having various patterns of loops incorporated therein.

Iclaim:

1. A loop foundation assembly for connecting material being formed to a supporting frame including parallel frame rails comprising a roller rotatably journalled on said frame, a flexible sheet member connected with said roller, a plurality of knotted loops attached to one edge of the sheet member, a connecting member extending through said loops, said material including a plurality of knotted loops receiving said connecting member whereby the connecting memberretains the loops on the material connected with the loops on the sheet member thereby detachably connecting the material to the sheet member, a split tube of resilient material encircling said roller and provided with a lateral entrance slit frictionally engaging the sheet member as it is wound therein thereby retaining tension on the material while working thereon, said connecting member being in the form of a rigid rodlike member threaded through the aligned loops on the sheet member and material, and having the end portions guided along the frame rails, each loop being formed from a continuous strand of thread having a series of spaced and connected knots along the edge of the sheet member with a small single loop formed between adjacent knots, said loops and knots being formed by forming a loop in the thread and twisting it and positioning it over the free end of a needle inserted through the sheet member and tightened to form a knot.
